At a weight of nearly 4,000 lb, the rigid bed is designed to absorb vibration for stable machining. In order to eliminate thermal growth during machining, all axes are driven by high precision double-nut ballscrews. The double pretension design provides outstanding positioning and repeatability with virtually no thermal growth.
All ballscrews are connected directly to the servo drive motors without gears or belts, eliminating backlash. Axes travel: 19.7 in X 66 in for Z- and B-axis.
Geared Head Spindle
The Big Bore spindle bore of 12.58 in (320 mm) diameter optimizes cutting efficiency when cutting oil pipeline or other types of pipe. Spindle motor is 60 hp with spindle torque rated at 7,045 Nm. The Big Bore spindle offers users high material removal rates, highest accuracy and excellent rigidity. It guarantees stability when run at high spindle speeds for high rpm precision machining. Chuck size: 32 in. Spindle nose: A1-20.
P4 class roller bearings and angular bearings secure excellent stability when heavy duty cutting. Ground bearing assembly parts in the spindle and headstock maintain consistent high accuracy.
In order to avoid the release of pre-pressure of the spindle bearing due to high speed accel/decel, heavy duty cutting and movement of the chuck cylinder and tension of the belt pulley, a double locking system separates the spindle bearing from the pulley. The three-step gearbox offers powerful low end torque for heavy cuts as well as high speed rotation for improved surface finish.
The L800A Big Bore is configured with an 700 rpm spindle for taking deep cuts. The main spindle delivers minimal noise and vibration even at the heaviest cutting, guaranteeing extremely stable machining and minimizing thermal transmission to the main spindle.
Built-in Tail Stock
The L800A Big Bore has an easy to use, programmable built-in tail stock to maintain superior accuracy and tailstock control. Taper: MT6. Quill diameter: 160 mm. Quill travel: 132 mm. Tail stock travel: 1,580 mm.
Turret
The Hyundai WIA L800A Big Bore has a 12-tool turret. Tool size: OD, 32 x 32 mm, and ID, 80 mm. Indexing time: 0.4 sec per step. This machine tool is ideal for the precise cutting of oil field pipe and other applications that demand handling long, cylindrical pipe and tubing in sometimes a remarkably harsh, high production environment.
Hyundai WIA Machine Corporation headquarters is located in the Gaeumjeong Factory in Changwon, South Korea. Products such as machining equipment, robots, industrial machinery, specialized machines, aircraft parts, and iron and steel products are manufactured at this 1.5 million sq ft facility, where 1,100 employees are devoted to production activity.
